' TROLLEY-POLE SUPPORT.

SPECIFICATION forming part of Letters Patent No. 781,404, dated January 31, 1905. Application filed October 29,1904. Serial No. 230,450.

T0 all wltom it may concern:

Be it known that I, THOMAS J. COPE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Trolley- Pole Support, of which the following is aspecification.

My invention consists of a trolley-pole sup-i port which is adapted to relieve said pole should the trolley jump the conductor or wire, so as to cause the same to drop preparatory to resetting of the troll e'y,, the means employed and the operation of the same being hereinafter set forth, and the novel features of the invention being pointedout in the claims.

Figure 1 represents a perspective view of a trolley-pole supportembodying my invention.

Figs. 2 and 3 represent vertical sections of:

portions of the same, showing certain parts in different positions. Fig. 4 represents a vertical section of the device, showingthe' pole in. the act of dropping. Fig. 5 represents a vertical section showing the pole in its dropped and lowermost position.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a trolley-pole, and B designates a'socket in which the lower end of said pole is fitted and are pivotally mountedon the ears D, the lat-; ter being attached by the base-plate D in any:

suitable manner to the body of a car.

E designates a swinging bracket which is pivotally mounted on the ears D and located between the arms C, it being connected with one end of the springE, whose other end is connected with the cross-head F on the outer end of the rods Gr, which extend from the ears D, and are provided with nuts H on opposite sides of said cross-head, whereby the tension of said spring may be adjusted. Rising from the opposite ends of said bracket are the fingers J, and between the latter on the upper surface of said bracket is the ratchet K, which is adapted to be engaged by the pawl or dog L, which is mounted on the arms 0 above said bracket and has a heel M, a comparatively flat face M, and an intermediate peak P, against which latter the spring-pressed plunger Q, is

in contact, said plunger being freely fitted in the lower portion of the socket B, the latter also containing the spring against said plunger.

I On thebas'e D is the screw S, whose point is adapted "to be engaged by the leg T of the bracketE as a stop and adjust the.v throw of said bracket when drawn up to its highest extent. r

The operation is as follows: The trolley is seated on the electric conductor or wire as usual, the position of the parts of the supports of the pole being shown in Fig. 2, the pole being permitted to oscillate with the bracket as usual, being subjected to upward pressure by the action of the spring E,while the point of the dog isheld engaged with a tooth ofthe ratchet K, owing to its pressure on the peak P. Should the trolley jump the conductor or wire, the pole rises when the heel of the dog L strikes the upper finger J,

, stop. The point of the dog having been raised by the depression of the heel causes the dog to clear the ratchet-K. (See Fig. 3.) In the turning motion of the dog the plunger Q, whichreadily yields, is pressed against the face M of the dog, thus holding the point of the latter in elevated position. As the pole is no longer controlled by the dog and ratchet, it begins to drop in the direction of the arrow, Fig. 4, and when it reaches its lowest point the front of the dog strikes the adjacent finger J, (see Fig. 5,) thus lowering the point of the dog so as'to subsequently engage with the ratchet K, the dog owing to its rotation having the plunger Q; now again seated on the peak P The conductor or motorman now works the pole up and down by a rope 'or chain, as usual, when owing to the spring G upward momentum is imparted tothe pole. The dog now rides over the ratchet until the trolley is seated, and the dog is then looked with the proper tooth of the ratchet, thus looking the pole with the bracket, the pole then operating as usual. 7

Various changes may be made in the details of construction shown without departing from the general spirlt of my invention, and

I. do not, therefore, desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a trolley-pole support, a pole, aswinging bracket, upward projections on opposite ends of said bracket, a bearing for said bracket, a ratchet on said bracket intermediate of said projections, a carrier for said pole and a dog on the carrier of said pole adapted to engage with said ratchet and contact with either of said projections.

2. In atrolley-pole support, a pole, a swinging bracket, upward projections on opposite ends of said bracket, a bearing for said bracket, a ratchet on said bracket intermediate of said projections, a carrier for said pole, a dog on said carrier adapted to engage with said ratchet and contact with either of said projections, and means for exerting pressure on said dog to hold it engaged with or disengaged from said ratchet.

3. In a trolley-pole support, a pole, aswinging bracket, upward projections on opposite ends of said bracket, 3. bearing for said bracket, a ratchet on said bracket intermediate of said. projections, a carrier for said pole, a dog on said carrier adapted to engage with said ratchet and contact with either of said projections, and an adjustable stop on said bearing with which said bracket may contact.

4. In a trolley-pole support, a pole, a swinging bracket, upward projections on opposite ends of said bracket, a bearing for said. bracket, a ratchet on said bracket intermediate of said projections, a carrier for said pole, a dog on said carrier adapted to engage with said ratchet and contact with either of said projections, and a plunger resiliently mounted in said carrier and adapted to bear against said dog to hold it engaged with or disengaged from said ratchet.

5. In a trolley-pole support, a swinging bracket, a bearing therefor, a carrier for the trolley-pole, a ratchet on said bracket, projections on said bracket on opposite sides of said ratchet, a dog on said carrier, said dog having a point, a back, a peak and a heel, said back and peak being adapted to be engaged by said plunger, said point beingmlapted to engage with said ratchet and contact with one of said projections and said heel being adapted to contact with the other projection.
